diversity around a natural carbohydrate ligand taking advantage of the rich chemistry of the nitrile functional group was demonstrated by synthesizing 24 derivatives of N-acetyllactosamine (LacNAc). The disaccharides prepared carried carboxymethyl, amidinomethyl, aminoethyl, and carbamoylmethyl substituents projecting from each of the six OH groups. The resulting LacNAc derivatives present new structural features
摘要通过合成24种N-乙酰基乳糖胺(LacNAc),证明了利用丰富的腈官能团化学物质在天然碳水化合物配体周围产生分子多样性的能力。制备的二糖带有从六个OH基团中的每个突出的羧甲基,a基甲基,氨基乙基和氨基甲酰基甲基取代基。所得的LacNAc衍生物具有新的结构特征,带有带负电,带正电或极性中性的小取代基,可对分子的整个外围进行采样。这些新的衍生物应该是一般研究碳水化合物-蛋白质相互作用,特别是设计N-乙酰基乳糖胺结合蛋白抑制剂的有用探针。
